Patented May 6, 1930 UNITED STATES Application filed November 29, 1926. Serial No. 151,388.

The invention has relation to portable refrigerators, having for an object to provide an improved refrigerator of this description. The invention consists in the novel construction and combinations of parts as set forth in the appended claims.

In the accompanying drawings, illustrating the invention, Figure 1 is a perspective view of the invention with the cover removed and the ice chamber located at one end; Figure 2 is a central longitudinal section of the invention with the ice chamber adjusted to middle position and the cover in place; Figure 3 is a detail sectional View of the joint of cover with body showing the spring top flange of the body lining in normal position; Figure 4 is a similar view showing the spring flange under tension; Figure 5 is a detail fragmentary perspective view of one corner of the refrigerator; Figure 6 is a view similar to Figure 2, of the top portion of the refrigerator showing the cover held in place by the top strap.

In these drawings the numeral 1 designates the body of the refrigerator, which is preferably of wood and of box form with straight vertical sides, square corners and flat horizontal top edges 1; and 2 is the metal lining therefor having also straight vertical sides and square corners, a suitable insulation 3 being provided between the metal lining and said body.

' The metal lining is provided with an outwardly extending separate straight spring top flange 6 for each side of said body, the lining being cut away at the corners at 7 between said anges and each flange having an inner curved upstanding ridge 8 and an outer reversely curved free end portion 9 resting slidingly upqn the top of said body.

The cover 4 is provided with a marginal felt packing strip 5 which engages the ridges 8 of the top flanges 6.

Due to the fact that the top flanges 6 of the lining are straight to conform to the straight sides of the refrigerator body and that they are separated by the cut away corner portions 7 of the lining; when the cover 4 is placed upon the refrigerator these spring Hanges will be pressed downwardly and flattened slightly PATENT oFFlcE i against their resiliency as shown in Figure 4, to cause the ridges 8 to have spring engagement with the felt packing strip 5, thereby making a better joint around the margin of the cover to retain the cold air.

The ice receptacle 10 is usually located at 5 one end of the refrigerator as shown in Figure 1 and is also provided with straight ver tical sides and square corners and has a cover l1. i

This ice chamber owing to the fact that 6U the body of the refrigerator is of the same width throughout and has straight vertical sides, is slidable or adjustable in said body so that it may be placed in middle position if r desired as shown in Figures 2 and 6, this being useful in some cases, and giving a better cooling eHect. The ice chamber is held in end position or in center position by any suitable means and preferably the cover 4 of the re- 70 frigerator mayhave its central thicker portion 12 engaged with the top of the ice chamber frictionally for this purpose as shown in Figures 2 and 6 and held in place pressed down tightly by means of a top strap 14 hav- 75 ing` a buckle 14.

The refrigerator is provided with wooden bail handles 13 whereby it may be readily transported from place to place.

I claim l. In a portable refrigerator, a quadrangular body having straight vertical sides and a top horizontal peripheral edge, a metal lining having straight vertical sides, each side of said lining having at the top thereof an outsa wardly extending straight spring top flange integral therewith and separate and spaced at its ends from the adjacent top flange and consisting of a curved upstanding ridge and' an outer reversely curved free edge resting slidingly upon the related horizontal top edge of a side of said body, and a cover, said spring top flange being adapted to be compressed against its spring tension under pressur of said cover to make a tight joint therewit i.

2. In a portable refrigerator, a quadrangular body and a quadrangular lining therefor having opposite straight vertical parallel sides intersecting in square corners, and a quadrangular ice chamber therefor having also straight vertical parallel sides intersecting in square corners and adapted to t Close- 1y within said lining and adjustable to endmost and to, intermediate positions therein, and means for holding the ice chamber in position as adjusted.

In testimony7 whereof I affix my signature. f EMIL A. FLORANG.
